In March, Yulia Prylipina measured her wealth in litres of drinking water. Four bottles of water that she managed to bring up to the ninth floor made her richer than Elon Musk. She continued to live in her flat, which was just madness by the standards of Mariupol in March. Not because of some unwisdom or bravado. Going down to the basement would just mean betraying her grandmother, who could not get up any more. Courage can be of different forms.
